Description

Verfahren zur Herstellung injizierbarer Extrakte der Roßkastanie Es ist bekannt, injizierbare Extrakte aus Roßkastanien unter Beseitigung ihrer haemolytischen Wirkung mittels Cholesterin dadurch herzustellen, daß auf eine Alkohol enthaltende Roßkasltanienextraktlösung Cholesterin, vorzugsweise in einem organischen Lösungsmittel, wie Äther, gelöst, zur Einwirkung gebracht wird, wobei die Einwirkungsbedingungen in Abhängigkeit von der Alkoholkonzentration des Extraktes gewählt werden, worauf die Lösung nach Abfiltrieren und Auswaschen des entstehenden Niederschlages auf den gewünschten Endgehalt gebracht wird. Process for the production of injectable extracts of the horse chestnut It is known to inject injectable extracts from horse chestnuts with the elimination of their haemolytic To produce effect by means of cholesterol, that on an alcohol-containing Cholesterol extract solution, preferably in an organic solvent, like ether, dissolved, brought into action, whereby the conditions of action be chosen depending on the alcohol concentration of the extract, what the solution after filtering off and washing out the resulting precipitate the desired final content is brought.

Die nach diesem Verfahren gewonnenen Lösungen eignen sich vor allem zur Behandlung bestimmter I)urchblutungsstörungen, und zwar auf dem Wege der Einspritzung in die Blutbahn. The solutions obtained by this process are particularly suitable for the treatment of certain I) circulatory disorders by means of injection into the bloodstream.

Es wurde nun gefunden, daß praktisch saponinfreie, therapeutisch wirksame, injizierbare Extraktlösungen von Roßkastanien auf noch einfachere Weise gewonnen werden können, indem man nicht von einer bereits fertigen alkoholischen Extraktlösung, sondern unmittelbar von Roßkastaniensamen ausgeht. Erfindungsgemäß wird dabei so vorgegangen, daß die zerkleinerten Roßkastaniensamen mit einer Lösung von Cholesterin in beispielsweise 800/obigem Alkohol extrahiert, die alkoholische Extraktlösung im Vakuum von Alkohol befreit und durch Zusatz von keimfreiem destilliertem Wasser auf den gewünschten Endgehalt gebracht und steril filtriert wird. It has now been found that practically saponin-free, therapeutic effective, injectable horse chestnut extract solutions in an even simpler way Can be obtained by not getting from an already finished alcoholic Extract solution, but comes directly from horse chestnut seeds. According to the invention the procedure is so that the crushed horse chestnut seeds with a solution extracted from cholesterol in for example 800 / above alcohol, the alcoholic Extract solution freed of alcohol in vacuo and distilled by adding sterile Water is brought to the desired final content and sterile filtered.

Zweckmäßig werden dabei frische, nicht wesentlich abgelagerte Roßkastaniensamen kalt, d. h. bei Temperaturen unter 200 C, extrahiert. Das noch lockere Zellgewebe erlaubt der Extraktionsfiüssigkeit auch bei niederen Temperaturen in das Innere einzudringen und die zu extrahierenden Wirkstoffe aufzulösen. Ist man gezwungen, von bereits abgelagerten und getrockneten Samen der Roßkastanie auszugehen, so wird dieser Samen zweckmäßig, z. B. durch Extraktion mit Äther, Leichtbenzin u. dgl., vorher entölt und anschließend bei mäßig höheren Temperaturen mit der alkoholischen Cholesterinlöswlg extrahiert. Fresh, not significantly seasoned horse chestnut seeds are useful cold, d. H. at temperatures below 200 C, extracted. The still loose cell tissue allows the extraction liquid to enter the interior even at low temperatures penetrate and dissolve the active ingredients to be extracted. Is one forced It is assumed that the horse chestnut seeds have already been seasoned and dried this seed expedient, e.g. B. by extraction with ether, light gasoline, etc., previously de-oiled and then at moderately higher temperatures with the alcoholic Cholesterol solution extracted.

Die nach diesem Verfahren erhaltenen Roßkastanienextraktlösungen zeigen keinerlei haemoiytische Wirkungen, sind also praktisch frei von Saponin, enthalten jedoch die für die therapeutische Behandlung der erwähnten Durchblutungsstörungen erwünschten Wirkstoffe und sind aus diesen Gründen für die Injektionstherapie geeignet. The horse chestnut extract solutions obtained by this process show no haemoiytic effects, are practically free of saponin, however contain those for the therapeutic treatment of the mentioned circulatory disorders desired active ingredients and are suitable for injection therapy for these reasons.

Das erfindungsgemäße Verfahren bietet den Vorteil einer überraschend einfachen Herstellung ohne besondere I(ontroll- und Überwachungsmaßnahmen. The inventive method offers the advantage of a surprising simple production without special control and monitoring measures.

Durch die das Extraktionsmittel bildende alkoholische Cholesterinlösung werden die Saponine bereits in der Gewebesubstanz der Roßkastaniensamen an Cholesterin gebun,den, ausgefällt und größtenteilts zurückgehalten, so daß lediglich ein geringer, in der Lösung schwimmender Teil des Gesamtniederschlages abzufiltrieren ist, was zweckmäßig zusammen mit der am Ende des Verfahrens stattfindenden Sterilfiltration erfolgt.Through the alcoholic cholesterol solution that forms the extractant the saponins are already in the Tissue substance of horse chestnut seeds in cholesterol bound, failed and mostly withheld, so that only a small, Part of the total precipitation floating in the solution is what expediently together with the sterile filtration that takes place at the end of the process he follows.

PATENTANSPROCAE: 1. Verfahren zur Herstellung injizierbarer Extrakte der Roßkastanie unter Beseitigung ihrer haemolytischen Wirkung mittels Cholesterin, dadurch gekennzeichnet, daß zerkleinerter Samen der Roßkastanie mit einer alkoholischen Cholesterinlösung extrahiert, die alkoholische Extraktlösung vom Alkohol zweckmäßig im Vakuum befreit, durch Zusatz von aqua pro injektione auf den gewünschten Endgehalt gebracht und steril filtriert wird. PATENTANSPROCAE: 1. Process for the preparation of injectable extracts the horse chestnut with elimination of its haemolytic effect by means of cholesterol, characterized in that crushed seeds of the horse chestnut with an alcoholic Cholesterol solution extracted, the alcoholic extract solution from the alcohol expedient freed in a vacuum by adding aqua pro injections to the desired final content brought and filtered sterile.
